Move over, Joe Francis. There’s a new sleaze director in town — blowhard billionaire Stewart Rahr has gone a step too far by sending a sex tape he filmed to many of his powerful New York contacts.

The hard-partying self-titled “King of All Fun” — perhaps too enthusiastically celebrating his $250 million divorce from his wife, Carol, after 43 years — pinged out a porn video of himself frolicking with three young women in the back of a limousine during the early hours of Monday, Page Six can exclusively reveal.

In the clip we’ve seen, the orange-faced pharmaceutical mogul can be heard murmuring appreciatively and urging the three brunettes to perform sex acts on each other. The short-skirt-wearing women comply with gusto, making out before moving onto more explicit acts, which Rahr, 67, closely films. The song “I Don’t Care, I Love It” can be heard in the background. He then sent out the sex tape to scores of outraged New Yorkers with the message, “What a trip, what a crew!”

One disgusted person who received the clip, thought to have been shot in the South of France, said, “This is something nobody asked to see, but I know Stewart sent it to many people unsolicited. It puts Kim Kardashian’s video to shame.”

Rahr, who sold his pharmaceutical company Kinray for $1.3 billion in 2010, has built friendships with power brokers including Bill Clinton, Michael Milken, Alicia Keys, Leonardo DiCaprio, Mark Wahlberg, Lionel Richie and Andrea Bocelli through his philanthropic work.

He was recently honored by The Make a Wish Foundation, which grants wishes to children that are diagnosed with terminal and life threatening illnesses and diseases, after donating $10 million. He was cheered on at the event by friends including David Koch, LL Cool J and Carmelo Anthony, who all sat at his table. But the filthy filmed foursome makes it clear not all of Rahr’s money goes to worthy causes.

Asked about the sex tape, Rahr’s lawyer Ben Brafman said, “However inappropriate or offensive the footage might appear to some, all the women are consenting adults who were engaged in friendly, voluntary and lawful behavior.”
